When burning up trail miles, our alpine tech tight keeps pace whether running, riding or traversing. Built with brush-resistant nylon and exceptional spandex flexibility, the Fortis™ Stretch Interlock fabric also delivers odor-resistance and wicking performance during dark-to-dusk circuits or point-to-point workouts. Fit for recovery during the longest days, resistance when the travel gets tough and endurance to match trail running epics such as Leadville races, Rim-to-Rim projects or Wonderland Trail circuits. A solo seven-inch thigh pocket stows cards, keys or a small phone for critical comms.
Fortis™, built with stretch interloc technology, is an extremely flexible nylon/spandex fabric. Its sueded finish offers a soft handfeel while moisture management and an antimicrobial treatment improves comfort and reduces odor during any active pursuit.
We completely offset the footprint of each order through our commitment to being climate neutral. As part of our mission we value being good caretakers of the mountain life and protecting the places where we play.
We are committed to building garments that are durable, timeless and continue to perform season after season. Over 50% of our product line incorporates preferred materials, which include organic cotton, recycled materials and responsibly-sourced down. We are committed to growing our preferred materials usage to 75% by 2025.
We believe a circular commerce system will design out waste and pollution, allowing for used clothing to be renewed and put back into use. Stio Second Turn™️ is our gear renewal program that allows customers to trade in and shop used apparel.
